After more than one hundred years of development, today's fire trucks have become a "big family" which includes a variety of categories, and the level of science and technology is staggering.
Tank fire truck is still the most popular fire fighting vehicle in the fire brigade. In addition to equipped with fire pumps and equipment, the vehicle also has a large capacity of water storage tanks, water guns, water cannons, etc., which can transport water and firefighters to the fire site to fight fires independently. Suitable for general fire fighting.
Extinguishing special fires with chemical fire extinguishers instead of water is a revolution of extinguishing methods for thousands of years. In 1915, the US National Bubbles Company invented the world's first dual powder fire extinguishing powder made of aluminum sulfate and sodium bicarbonate. Soon, the new fire extinguishing material was also used on fire engines.
A large number of high multiple air bubbles that can be sprayed up to 400-1000 times can be quickly sprayed, so that the surface of the combustible material is isolated from the air and is especially suitable for fighting oil fires such as oil and its products.
It can extinguish flammable and flammable liquids, flammable gas fires, live equipment fires, as well as general material fires. For large-scale chemical pipeline fire, the fire fighting effect is particularly remarkable, and it is a common fire fighting vehicle in petrochemical enterprises.
With the improvement of modern building level, more and more high-rise buildings, fire trucks have changed, and ladder fire trucks have appeared. The multi-level ladder on the ladder fire truck can directly send the firefighters to the fire site of the high-rise building for timely disaster relief, and can rescue the victims trapped in the fire site in time, greatly improving the ability of fire fighting and disaster relief.
Nowadays, there are more and more specialized distinctions between fire engines, such as carbon dioxide firefighters mainly used to fight fires such as precious equipment, precision instruments, important cultural relics and books and archives; airport rescue firefighters dedicated to the rescue of aircraft crashes and rescue workers; and lighting firefighters for night fire extinguishing and rescue workers. It is especially suitable for fire fighting in underground buildings and warehouses, etc.
